| Cost-efficient Archive Cloud Storage with Tape: Design and Deployment | FAST '26 | 2026-02-24 |
TapeOBS claims tape reduces TCO 4.95× and CO2e by 97% and runs in production storing hundreds of petabytes since 2024. It uses a 4% HDD staging pool to make a… | ||
| Weaver: Efficient Multi-LLM Serving with Attention Offloading | USENIX ATC '25 | 2025-07-07 |
Weaver implements attention offloading that lets hot models borrow KV cache memory on cold-model GPUs by shipping QKV vectors and running attention there… | ||
| Achieving Wire-Latency Storage Systems by Exploiting Hardware ACKs | NSDI '25 | 2025-04-28 |
Juneberry implements an Ordered Queue (OQ) that uses hardware ACKs as commit signals from RDMA NICs so clients commit neoex storage requests in one round trip… | ||
| ShiftLock: Mitigate One-sided RDMA Lock Contention via Handover | FAST '25 | 2025-02-25 |
ShiftLock claims to cut RDMA lock retries by enabling direct client-to-client handovers so waiting clients spin locally instead of hammering the server; it… | ||
| TeRM: Extending RDMA-Attached Memory with SSD | 22nd USENIX Conference on File and Storage Technologies (FAST '24) | 2024-02-27 |
Extends RDMA-attached memory by mapping SSD-backed virtual space (64 GB VM with 32 GB RAM in tests) and replacing NIC page-fault handling with user-space… | ||
| Replicating Persistent Memory Key-Value Stores with Efficient RDMA Abstraction | OSDI 2023 | 2023-07-10 |
OSDI '23 - Replicating Persistent Memory Key-Value Stores with Efficient RDMA Abstraction
Qing Wang, Tsinghua University, Youyou Lu, Tsinghua University, Jing… | ||
| Revisiting Secondary Indexing in LSM-based Storage Systems with Persistent Memory | USENIX ATC '23 | 2023-07-10 |
Claims a complete design called PERSEID that uses a PS3 two-layer PM index, a hybrid PM-DRAM hash validation to avoid expensive primary-table reads, and two… | ||
| Citron: Distributed Range Lock Management with One-sided RDMA | FAST '23: 21st USENIX Conference on File and Storage Technologies | 2023-02-21 |
Citron implements a distributed range lock manager that uses one-sided RDMA and a static segment tree layout so clients bypass server-side CPUs. It maps any… | ||
| Patronus: High-Performance and Protective Remote Memory | FAST '23: 21st USENIX Conference on File and Storage Technologies | 2023-02-21 |
PATRONUS implements a protective RDMA remote-memory system that preserves one-sided access while using memory windows and tokenized permissions to enforce… | ||
| Pacman: An Efficient Compaction Approach for Log-Structured Key-Value Store... | USENIX ATC '22 | 2022-07-11 |
Pacman is a persistent-memory aware compaction design for log-structured key-value stores that offloads reference search to service threads, uses tagged… | ||
| AlNiCo: SmartNIC-accelerated Contention-aware Request Scheduling for Transaction... | USENIX ATC '22 | 2022-07-11 |
USENIX ATC '22 - AlNiCo: SmartNIC-accelerated Contention-aware Request Scheduling for Transaction Processing

| Nap: A Black-Box Approach to NUMA-Aware Persistent Memory Indexes | 15th USENIX Symposium on Operating Systems Design and Implementation (OSDI '21) | 2021-07-14 |
Nap converts existing concurrent persistent‑memory indexes into NUMA‑aware ones by adding a NUMA‑aware layer that keeps per-node partial views in PM for local… | ||
| Concordia: Distributed Shared Memory with In-Network Cache Coherence | FAST '21 | 2021-02-23 |
Concordia implements a DSM that pushes cache coherence into programmable switches, using a hybrid protocol FLOWCC that stores per-block metadata and a… | ||
